Cell Unit JEOPARDY!! Microscopes, Cell Theory, and Cell Size Prokaryotes and Eukaryotes 1 Prokaryotes and Eukaryotes 2 Cell Transport 1 Cell Transport 2 10 20 30 40 50 10 20 30 40 50 10 20 30 40 50 10 20 30 40 50 10 20 30 40 50 10 Microscopes, Cell Theory, and Cell Size Light microscopes are useful for… 10 Microscopes, Cell Theory, and Cell Size *viewing living objects *classroom use *magnifying things not seen by the naked eye 20 Microscopes, Cell Theory, and Cell Size An electron microscope is useful for… 20 Microscopes, Cell Theory, and Cell Size *greater magnification and resolution *viewing the inside of cells (TEM). *viewing the outside of cells (SEM) 30 Microscopes, Cell Theory, and Cell Size *Why are cells so small? 30 Microscopes, Cell Theory, and Cell Size *to ensure efficient transport of nutrients and waste inside a cell *to ensure chemical reactions occur quickly and efficiently inside the cell 30 Community 1 40 Microscopes, Cell Theory, and Cell Size What happens as a cell gets larger? 40 Microscopes, Cell Theory, and Cell Size *its surface area does not increase at the same rate as the volume 50 Microscopes, Cell Theory, and Cell Size What are the three components of the cell theory? 50 Microscopes, Cell Theory, and Cell Size *cells come from preexisting cells *cells are the basic unit of structure and function in living organisms *all things are composed of cells 10 Prokaryotes and Eukaryotes 1 DNA is found in what part of a prokaryotic cell? 10 Prokaryotes and Eukaryotes 1 *nucleoid region 20 Prokaryotes and Eukaryotes 1 What is the size of a prokaryotic cell? 20 Prokaryotes and Eukaryotes 1 *1-10 um 30 Prokaryotes and Eukaryotes 1 What is the size of a eukaryotic cell? 30 Prokaryotes and Eukaryotes 1 *10-100 um 40 Prokaryotes and Eukaryotes 1 What is the function of the endoplasmic reticulums? 40 Prokaryotes and Eukaryotes 1 Smooth ER- lipid synthesis, carb metabolism, detoxification Rough ER- protein folding and transport 50 Prokaryotes and Eukaryotes 1 List three organelles that are both double membraned and contain DNA? 50 Prokaryotes and Eukaryotes 1 *Nucleus *Mitochondria *Chloroplast 10 Prokaryotes and Eukaryotes 2 What is found in an animal cell and not a plant cell? 10 Prokaryotes and Eukaryotes 2 *centrioles *lysosomes *small, numerous vacuoles 20 Prokaryotes and Eukaryotes 2 .What is found in a plant cell and not an animal cel? 20 Prokaryotes and Eukaryotes 2 *chloroplast *cell wall *large central vacuole 30 Prokaryotes and Eukaryotes 2 What are some components of the cytoskeleton of an animal cell? 30 *microfilaments *microtubules *cilia *flagella Prokaryotes and Eukaryotes 2 40 Prokaryotes and Eukaryotes 2 What are the roles of the golgi complex? 40 Prokaryotes and Eukaryotes 2 *stores, modifies, packages, and tags proteins 50 Prokaryotes and Eukaryotes 2 *Draw and label a diagram of the mitochondria 50 Prokaryotes and Eukaryotes 2 * 10 Cell Transport 1 How are the phospholipids arranged in the cell membrane? 10 Cell Transport 1 As a bilayer*phosphate heads facing the outside and inside of the cell *fatty acid tails facing each other 20 Cell Transport 1 *What is the role of Cholesterol in the cell membrane? 20 Cell Transport 1 *Stabilizes the cell membrane *prevents the cell membrane from freezing at low temperatures. 30 Cell Transport 1 What makes the cell membrane a Fluid Mosaic? 30 Cell Transport 1 Fluid- *fatty acid tail kinks prevent the phospholipids from packing too tightly, *cholesterol prevents cell membrane from freezing at low temperatures Mosaic- the arrangement of all of the various molecules in the cell membrane resemble a mosaic 40 Cell Transport 1 What are the functions of the cell membrane? 40 Cell Transport 1 *regulate what moves in and out of the cell/ semipermeable *allows cell to attach to other cells and surfaces *immune response *makes up organelles 50 Cell Transport 1 What influences the movement of molecules across the cell membrane? 50 Cell Transport 1 *size, charge, polarity, concentration, and the permeability of the cell membrane 10 Cells My name is Bond, Ionic Bond; Taken, not shared! 10 Population Growth From: Mariano Cecowski <MCecowski#NoSpam.sif.com.ar> Q: if both a bear in Yosemite and one in Alaska fall into the water which one disolves faster? A: The one in Alaska because it is HIJKLMNO 10 Population Growth Alimentary: What Sherlock Holmes said to Dr. Watson. Urinate: What a nurse would say if a patient asked her what room he's in. Urine - The opposite of "You're out!" Benign: What we want when we are eight. Intestine - Currently taking an exam CARDIOLOGY: advanced study of poker playing TERMINAL ILLNESS: getting sick at the airport 10 What is diffusion? Cell Transport 2 10 Cell Transport 2 *passive transport of molecules across the cell membrane *must be small and nonpolar 10 Population Growth 20 Cell Transport 2 An animal cell in a hypertonic solution will.. 20 Cell Transport 2 *shrivel up 30 Cell Transport 2 Upon drinking salt water, what kind of condition are you creating for your cells? What will happen to them? 30 Cell Transport 2 *the outside of the cells will be hypertonic compared to the inside of the cells. *your cells will lose water, shrivel up, and become dehydrated. 30 Population Growth 40 Cell Transport 2 What are the three types of endocytosis? Explain each. 40 Cell Transport 2 *the cell membrane pinches in around the molecules to enter the cell and forms a vesicle, which is brought into the cell. *Phagocytosis (solid) *Pinocytosis (liquid) *receptor-mediated (highly specific) 50 Cell Transport 2 How is active transport different than passive transport? 50 Cell Transport 2 *molecules move from low to high concentration *against the concentration gradient *requires energy *includes the simple model, endocytosis (phagocytosis, pinocytosis, and receptor-mediated endocytosis) and exocytosis.
